The operator that tries can judge easily whether or not display of the observation region on the expansion image is correct the lumen internal organs of the suffering inspection body as the expansion image in the medical image display device which it displays. Correspondence acquiring false echo factor calculation means and the aforementioned false echo factor which calculate the false echo factor of particular position in the medical image display device which has the expansion image creation means which create the expansion image of the lumen internal organs of the suffering inspection body and the indicatory means which display the aforementioned expansion image, according to the position in the aforementioned expansion image to the aforementioned expansion image, the control means which it makes display and, it has. In addition, the control means which make the aforementioned expansion image display on the basis of false echo factor calculation means and the aforementioned false echo factor which calculate the false echo factor of particular position in the medical image display device which has the expansion image creation means which create the expansion image of the lumen internal organs of the suffering inspection body and the indicatory means which display the aforementioned expansion image, according to the position in the aforementioned expansion image and, it has.被検体の管腔臓器を展開画像として表示する医用画像表示装置において、展開画像上の観察部位の表示が正しいか否かを操作者が容易に判断できるようにする。被検体の管腔臓器の展開画像を作成する展開画像作成手段と、前記展開画像を表示する表示手段を備えた医用画像表示装置において、前記展開画像中の位置に応じて当該位置の偽像率を算出する偽像率算出手段と、前記偽像率を前記展開画像に対応付けて表示させる制御手段と、を備える。また、被検体の管腔臓器の展開画像を作成する展開画像作成手段と、前記展開画像を表示する表示手段を備えた医用画像表示装置において、前記展開画像中の位置に応じて当該位置の偽像率を算出する偽像率算出手段と、前記偽像率に基づいて前記展開画像を表示させる制御手段と、を備える。
